. V In v harvesting smallA grain it kis common practice to employ combination f harvesterthreshers, generally known as combines, Which type. Q of machine L is. drawn through the field and simultaneously cutsand threshes standing grain, such method being recognized as time and labor saving and therefore highlgy7 economical. However, conditions are at times quiteunfavorablefor harvesting, and so far as I am aware-no combine is capable of gather.-

inglall the grain or'substantially so, for the reason that aconsiderable percentage of the headed stalks have become broken off ,or bent over through attacks by insects, ydamage by storms and otherwise, so that the down heads of grain remain in the stubble close toror yon the ground and are .passed over ineii'ectively bytheheader during :the operations of cuttingJand conveying the grain to the .threshen These'broken stalks and down head-s are scat;- tered throughout `the entirek crop area, some.- timescomprising as muchas one-third otall the stalks, and, to the best-otmy-knowledge, it hasb'een impossible to gather. thesel fallen heads: from thee-stubble or ground bycombines, reapers, binders'. or other-machinery as at present constructed and' operated. Underl the conditions stated the'grain grower suders a materia-l loss of the headed grain lyingon the ground or sustained inthel stubble, as ordinarily it is not practical or possible, after a movin harvesting machine has once traversed the eld, to go backover the ground and endeavor `to pick up the down gra1n,1n fact such method would `behighly objectionable for economicall reasons as severalfoperationswouldl be required in the field for saving'such grain. It Will `be apparent, therefore, that theloss of small grainV from causes such as indicatedis very'material, and it is my object to preventsuch loss by providing meansy in connection with a combine or other harvesting machine for combiningthe stubble and raking the ground over Whichjthe 'mas? chine is-passing, :thus gathering and, gleaning the -fallen headed rain lying bel/0W the level of the cutting mec anisms, which I conf vey'tolthe harvester platform of" a combine to be deliveredto'the thre'sher ,With the grain being cut by the header,"in ,which Vmanner `l am enabled to effectively gather and save grain 4which would otherwise be lost, y and n thresh the same with the grain being cut, thus sawing substantially the entire l-cropy in one operation of the machinery through a field of headed grain.

' In the vaccompanying drawings, forming part-hereoL-Figure 1 `is -an elevation of a combination harvester-thresher With my improved gleaner attached -tothe harvester; Fig. 2, an enlarged end elevation of the harvester and glean'er the latter being partly in section,indicating the relation ot' saidv elementsjto standing grain; Fig. 3,"a diagrammaticvv-iew 'showing av plurality of gleaners andftheir' relation to ayharvester, the latter being but partly shown; Fig. ll, a detail plan vof .the'gleaner; Fig.5`is a modified form of the gleaner, and Fig. 6 is a plan View of said modified forinf` Inthe drawings the numeral 1() indicates the thresher element of fa combine, supported by rear and front Wheels 11, 12, respectively, and13 anrengne for operating-the machinery. The header element may be of any desired construction, and which embodies a` reel 14, :platform- 15,` sickle -16,ja nd other equipmen'tzofvwellknown character. l

I- may employ one or more ,f ,rleaners,A 18, according to` the size of the header, three be-` ing indicated in. `Fig. 3, and flexibly mounted S9. that they may move-independently when traversing. `gro un d, irregularities. The gleaner; comprisesan vaxle 19 which supports Wheels 2O provided with 4lugs 21 for gripping the fgroundpand constitute a ground driveV forvthe gleaner mechanisms, and upony which axle sprockets22are mounted to rotate there- Y with.. Shafts 23 Iforming part of the upper end .ofthe gleaner arefsecured, at 241, to the header, as indicated in Figs. 1 and 3, and upon which shafts sprockets or idlers 25 are mounted in alinement with sprockets 22 on the axle 19, which sprockets are connected by chains 26 forming part of a slatted carrier 27, which carrier travels over an imperforate flooring 29, as indicated in Fig. 5. At each side of thecarrier links 28 are secured to the shafts 23 and axle 19, so connected to said shafts as to oscillate, and thereby permit' the wheels 2() to follow ground irregularities. A shaftk or axle 17 extending from the thresher and having suitable connections .subf stantially as disclosed in the MacGregor Reissue Patentl'o;V 17 ,368 'dated July f6, :1926, supports-an arm 28 for holdingthe'header'y through the space formed dby thelinls 28, as indicated in Fig. 4, andgisshown as broken platform in position, which Iarm at the point where it passes over the axle 19 o f t-he gleaner wheels, .,forpur-poses v of lclearrless. Z j, f l v Axle 19 is, equipped with la series 'of yield ing 'tines 30, which'rotate with the axle, and are so time'd'in their rotation 'in relationto the Vcarrier '27 'that there will be no contact or interference-'between these parts when the sprockets .'22 vrotate to actuate the lcarrier in s the direction indicated. Th'ecarrier and its actuating parts in 1 beef any-desired arrangement and nee not be more'speiciiically described herein. f

Upon a fra-me 32 Imount aseries `'of curved lingers 33 spaced acrossy the wid-tlrof the gleaner, which act as a r-ake'forrtlioroughly combing the stubble and @arranging such down heads,` as '34, inv position to be picked up by the tines 30 and carried v'upwardly thereby and onto carrier 27 by which they are conveyed forwardly onto theheader platform, where suchv material, as indicated, ibecomes part of the crop-being cutto be coni veyed therewith into the thresher, which operation is apparent from Fig. 3. In the Vfragmentary plan, Fig. 4, froinwhich the lingers 33 and other parts have been omitted for purposes of clearness, thev bearings 24 are more plainly shown, which are secured to the header, :and in which `the shafts '23 are supported, the ends of which sustain the upper carrier structure.

In the modified lform shown in Figs. 5 and 6I attach a second unit to that just described, by connecting members 28 supporting shaft 19 upon which latter in any suitable manner l mount carrying wheels-'35 free to turn about sai-d shaft. TinesBG are also mounted on the axle 19l to rotate therewith and inreverse direction to the wheels '35 and the tines '30 of the forward unit, `by m'eansof a sprocket-and-chain system 37 at 'one side of the implement, las indicated -in'Figp'. It will 'be noted that rake'fingers, such as 3'3'in Fig. '2, are 'omitted 'from the modiiied form, so 'that any material which may be picked up .Fig...6.
